(B) Appearance of an OVM-null egg. (C) Average weight of eggs from WT and OVM^−/− hens at 10 mo of age. (D, E) The OVM-null egg had watery whites compared with wild-type. (D) One-week-old WT and (E) OVM-null eggs. Solid and dotted lines indicate the edges bordering thin and thick albumen, respectively. (F) Average height of egg albumen in WT and OVM-null eggs. Error bars indicate standard deviation. ∗∗P < 0.01, one-way ANOVA with the Tukey's test.
